feat[bindings]: expose power level thresholds in corresponding timeline event

[JoFrost]

Hello! This PR exposes power-level thresholds in OtherState::RoomPowerLevels for the FFI timeline.

It includes action requirements such as ban, kick, invite, redact, state_default, events_default, per-event overrides and notifications. This gives FFI clients direct access to the effective power levels of a room, which were previously unavailable.

• Public API changes documented in changelogs (optional)

Hello @poljar! Quick check on this PR.

I wanted to confirm whether this aligns with the intended API direction, or if you’d prefer to wait for #5937 to be merged and then have this rebased on top of it.
If this approach doesn’t hit the mark, I’m happy to close the PR.

Thanks.

Yes, let's do that, I don't think there's much blocking #5937 so it should be merged soon™.

All done @poljar. I rebased on main, and used what was introduced in #5937 for this PR.
